The pill that monitors vital signs, such as heart rate, respiratory rate, and core body temperature, works through innovative technology embedded in an indigestible capsule. The capsule, which is the size of a multivitamin, contains microphones to pick up the sounds of the heart and lungs, a thermometer to measure core body temperature, and a battery for power. As the capsule travels through the digestive system, it can track these vital signs with high accuracy. The captured data is then transmitted at regular intervals to an external receiver, allowing for real-time monitoring and the potential for triggering alerts in case of abnormal vital sign readings. The capsule is designed to be excreted from the body a few days after ingestion. This technology has the potential to revolutionize health monitoring, enabling remote tracking of vital signs and early detection of health issues.
